Troubleshooting
With proper installation, operation, and maintenance your gas appliance will provide years of trouble-free service. If you do
experience a problem, this troubleshooting guide will assist a qualifi ed service person in the diagnosis of a problem and the
corrective action to be taken. This troubleshooting guide can only be used by a qualifi ed service technician.
Symptom Possible Cause Corrective Action
1. After repeated trig-
gering of the piezo
button, the spark ignitor
will not light the pilot.
a. Defective ignitor. Check the spark at the electrode and pilot. If no spark and electrode
wire is properly connected, replace the ignitor.
b. Defective pilot or
misaligned electrode
(spark at electrode).
Using a match, light the pilot. If the pilot lights, turn off the pilot and
trigger the piezo button again. If the pilot lights, an improper gas/air
mixture caused the bad lighting and a longer purge period is recom-
mended. If the pilot will not light, ensure the gap at the electrode and
pilot is one-eighth (1/8) inch to have a strong spark. If the gas is OK,
replace the pilot.
c. No gas or low gas
pressure.
Check the remote shut-off valve from the appliance. Usually, there is
a valve near the gas main. There can be more that one (1) valve from
the appliance and the main.
d. No LP in tank. Check the LP (propane) tank. You may be out of fuel.
2. The pilot will not stay
lit after carefully follow-
ing the lighting instruc-
tions.
a. Defective thermo-
couple.
Check that the pilot fl ame impinges on the thermocouple. Clean and /or
adjust the pilot for maximum fl ame impingement.
Ensure that the thermocouple connection at the gas valve is fully
inserted and tight (hand tighten plus 1/4 turn).
Disconnect the thermocouple from the valve, place one millivolt lead
wire on the tip of the thermocouple and the other meter wire on the
thermocouple copper lead. Start the pilot and hold the valve knob in. If
the millivolt reading is less than 15mV, replace the thermocouple.
b. Defective valve. If the thermocouple is producing more than 15 millivolts, replace faulty
valve.
3. The pilot is burning,
there is no gas to the
burner, the valve knob is
in the ON position, and
the ON/OFF switch is in
the ON position.
a. ON/OFF switch or
wires defective.
Check the ON/OFF switch and wires for proper connections. Place the
jumper wires across the terminals at the switch. If the burner comes on,
replace the defective switch. If the switch is OK, place the jumper wires
across the switch wires at the gas valve. IF the burner comes on, the
wires are faulty or connections are bad.
b. Thermopile may
not be generating
suffi cient millivoltage.
If the pilot fl ame is not close enough physically to the thermopile, adjust
the pilot fl ame.
Be sure the wire connections from the thermopile at the gas valve ter-
minals are tight and that the thermopile is fully inserted into the pilot
bracket.
Check the thermopile with a millivolt meter. Take the reading at TH-TP
& TP terminals of the gas valve. The meter should read 325 millivolts
minimum, while holding the valve knob depressed in the pilot position,
with the pilot lit, and the ON/OFF switch in the OFF position. Replace
the faulty thermopile if the reading is below the specifi ed minimum.
With the pilot in the ON position, disconnect the thermopile leads from
the valve. Take a reading at the thermopile leads. The reading should
be 325 millivolts minimum. Replace the thermopile if the reading is
below the minimum.
